Appendix A Cost Evaluation
Phosphate Treatment of Residential Properties at the Omaha Lead Site, Omaha, Nebraska
Assumptions for Cost Evaluation September, 2008
This evaluation presents the costs to implement a phosphate treatment remedial action at the Omaha Lead Site in Omaha, Nebraska. The evaluation contains the cost breakdown of the tasks and procedures required to implement the remedial action.
Following is an outline of the basic project assumptions; phosphate treatment procedures; miscellaneous cost impact issues, and other considerations that directly and indirectly affect the remediation process and impact the cost estimate:
A. Basic Project Assumptions: 1. Unit residential treatment area of 7,890 square feet (sf) [property area equivalent to
25% of nominal survey acreage of a typical property at 10,890 sf, minus 3,000 sf for improvements, landscaping, and other areas = 7,890 sf ]
2. Contractors for project shall function as follows: a. Prime Contractor
• Mobilization to property • Property assessment • Property area preparation (prior to treatment process) • Install protective barrier/erosion control • Roto-tilling #1 (to depth of about 15 cm) • Initial Application of Chemicals (Phosphoric Acid and Potassium
Chloride) • Roto-tilling #2 • Application of addt’l 5g Phosphate (P) Kg soil • Roto-tilling #3 • Lime stabilization of soil / pH adjustment • Soil preparation for sod placement (see subcontractor below) • Re-install lawn features • Remove protective barrier/erosion control • Demobilization from property
b. Subcontractor(s) • Lawn Service Subcontractor
• Lay sod (following application of chemical agents by Prime Contractor, and soil preparation for sod placement)
• Replacement of damaged plantings / shrubs, etc
A-1
3. 85% Phosphoric Acid (PA) is applied at rate of 10 U.S. gallons per 86.1113 sf. (37.8 Liters per 8 sq. meters); (note: per Harcros Chemicals, Inc., PA is typically purchased by the pound at a weight of 13-14 lbs of raw acid/gallon; use 13.2 lbs/gal. PA is incorporated into the soil at approx. 6” depth during roto-tilling operations.
Volume of PA required per property: 7,890 sf /property x 10 gal / 86.1113 sf = 916.256 gal PA / property
Weight of PA required per property: 916.256 gal PA / property x 13.2 lbs / gal = 12,095 lbs / property
4. Potassium Chloride (KCl) (fertilizer grade) is applied at a rate of 335 lbs / 7,890 sf property (1.66 kilograms per 8 sq. meters). The KCl shall be applied in conjunction with the application of the Phosphoric Acid.
5. Lime is applied at a rate of 1837 lbs / 7,890 sf property (9.1 kilograms per 8 sq. meters). The Lime will be applied and incorporated in the soil by roto-tilling and grading for drainage, and compaction to 85% Proctor. Lime incorporation occurs after a period between 3 to 10 days following the application of the PA and KCl.
B. Listing of Chemical Treatment Procedures: Step 1 Property Assessment (e.g., identify buried utility locations)
Step 2 Property preparation (prior to treatment process) Step 3 Install protective barrier/ erosion controls around property Step 4 Roto-tilling #1 of soil Step 5 Apply Phosphoric Acid chemical Step 6 Apply Potassium Chloride chemical Step 7 Roto-tilling #2 of soil Step 8 Apply Application of addt’l 5g Phosphate (P) Kg soil Step 9 Roto-tilling #3 of soil Step 10 Incorporate Lime into soil (incl Rototilling #4) Step 11 Fine Grade / compaction of disturbed soil to prepare for sod placement Step 12 Placement of Sod Step 13 30 day watering period to establish sod (provide cost allowance to owner) Step 14 Re-install lawn features Step 15 Replacement of damaged plantings / shrubs, etc. (note: provide cost allowance) Step 16 Remove protective barrier/erosion controls
C. Direct-Indirect cost impacts and considerations: 1. All properties are considered to be residential.
2. Costs of chemicals and sod placement are based on delivery to Omaha, NE.
3. The location of buried utilities issues (i.e., cable T.V., sprinkler systems, underground electrical) are a concern. An allowance for locating the utilities has been included in the estimate.
4. Costs associated with pet control issues are not addressed in this estimate.
A-2
5. HAZWOPER - OSHA Compliant Training costs are considered requirements for all personnel and included in the analysis.
6. Assumed Daily Log / Journaling tasks for remediation program inherent to all activities.
7. Cost evaluation does not provide for allowances where property conditions may exist in which owner has invested substantial resource into lawn care / maintenance, etc.
8. When soil is roto-tilled, it may bulk in volume approx. 15%, and require re-compaction prior to sod placement. (See Steps 5 through 10 of treatment procedures.)
10. Analysis assumes erosion control barrier will be required in addition to the protective barrier.
11. Analysis does not provide for Testing /Sampling following remediation procedures.
12. A cost allowance is made for areas of properties that may require some re-sodding at future date. For purpose of the cost evaluation, the basis is 10% of total residential properties requiring 5% sod re-placement.
13. No cost allowance is made for temporary displacement of individuals / pets / livestock, etc., during the remedial process.
14. Prime and Subs will need to mob / demob to each residential property. An allowance for mob / demob of equipment and personnel and documentation procedures is provided in the analysis.
15. Costs do not include oversight by agency personnel.
16. It is assumed contractor personnel shall be required to wear protective clothing during all chemical applications and presence on the property prior to sod placement. Respirators will be required during application of the phosphoric acid. (See item 5 above)
17. Analysis does not include costs associated with obtaining access to properties, characterization costs, or post-treatment evaluation costs.
18. Costs relating to damage of property features (i.e., sidewalks, drives, ornaments) are not included.
19. A cost allowance for watering the sod for 30 days is provided for in the estimate.
20. Costs associated with limitations and encumbrances to property access are not included.
21. Risks associated with the acidic and caustic nature of applied chemicals are not addressed. Risks may include ecological impacts and associated costs due to stormwater runoff which discharges into streams and air-borne particulates which become in contact with property features (i.e., housing, automobiles, and other property features.)
A-3
22. Risks, concerns, and issues which are associated with stormwater runoff discharged onto adjoining properties are not evaluated in this analysis.
23. A 10% contingency is added to the estimated phosphate treatment cost to allow for unforeseen conditions and circumstances relating to remedial operations.
24. Contractor delivery capability of chemicals in residential areas is an issue due to the limited size requirements of delivery vehicles and limited roadway features typically found in residential areas. Associated risks / costs impacts due to delivery of chemicals to a property are not included.
25. Availability and costs of the chemicals are affected by seasonal demands supplies on manufactures from agri-business, or other industries.
26. Due to the extensive gross chemical quantities required for a remediation program of residential properties, a controlled storage and staging facility of chemicals will be required for the OLS program. The facility would warehouse and allow for breakdown of delivered products into manageable and effective units. It would be required for the facility to adequately shelter the products from the elements and meet public safety needs. Sufficient personnel and equipment would be required to manage and maintain operations at the storage and staging facility. Although the specific requirements for the facility are not known, an allowance has been included in the analysis.
27. Davis-Bacon wage rates are used as basis of labor costs, from DB General decision NE20080001, dated 08/08/2008. Equipment costs are abstracted from 2007 MCACSES MII Region 5 Equipment database, then escalated to 2008 costs.
28. Costs are in current 2008 U.S. dollars (as of September 2008).

Allow $500 for a one week (40 training session) which trains all personnel for duration of entire abatement
Personnel requiring training are those involved in all preparation and treatment efforts prior to sod placement Training Costs are distributed over balance of 3,747 properties at the Omaha Lead Site project (Sept 2008). Est. 7 people trained ; $500 per wk training cost / 7 people = $71.43 cost per person ; assume $71.43 / 3,747 prop = approx. $0.02 course cost / per person / property; training costs paid for training: labor costs paid during training: 40 hrs x [assume 5 persons x $23.50 avg / hr+ 2 persons x $22.75 / hr] = $6520 div. by 3,747 = $1.74 thus $1.74 + $0.02 = $.1.76……use $1.76 / property = Avg. HAZWOPER - OSHA Compliant Training cost per Property
Controlled Chemical Storage and Staging Facility: Costs associated with a controlled storage and staging facility of chemicals should be incurred for the Omaha Lead Property abatement program. The facility would warehouse and allow for breakdown of delivered products into manageable and effective units. An Estimated amount of $3,000,000 is required for property / facility acquision; facility operations over estimated 7 year period; and de-commissioning of facility. Thus, $3,000,000 / 3,747 properties = $800.64 cost impact per property; say $800 $ 200.00 $ 200.00 $ 400.00
